Due to the fact that there are no direct ferries between Croatia and Greece at this time and travelling by land is complicated, taking a flight would be the best option of travelling between these two countries.
For travelling between Dubrovnik region and Greece's capital Athens, you can choose from two air carriers - Croatia Airlines and Aegean Airlines.
Croatia Airlines, the Croatian national air company, operate direct flights between Dubrovnik and Athens in the summer. Flights usually start in April and terminate at the end of October with frequency of three flights a week (on Tuesdays, Thursdays and Sundays).
The journey time between Dubrovnik and Athens is around 2 hours.
Aegean Airlines, the largest Greek airline, fly between Athens and Dubrovnik each year during the summer season when many passengers fly on this route. The flights usually start from the beginning of April until mid - October.
Flights will be available 2 times a week (Tuesday, Saturday) in low season and 4 times a week in high season (Monday, Tuesday, Thursday and Saturday). These flights are direct and the journey takes around 1 h 30 minutes.
